Hi All,
Today is my day for headaches.
We assembled a flex circuit (put a couple of connectors on) and did the Ionic contamination test after our standard cleaning procedure and failed.
After much scratching of heads we decided to take a bare flex - solder it - not add the connectors and test - passed the ionic test easily.
We then took the connectors and put them in the ionic unit - one hit 76 ug/cm2 as received and 6.9 after cleaning. The other was 9.6 ug/cm2 as received and 6.6 after cleaning.
So my question is - do the connector manufacturers have to sign up for a certain cleanliness level and second question what the *&?" do I do now.
Regards Steve Kelly
